I've been all over the internet and still cant get my iphone 3gs working the way I want.

Long story short it crashed and I had to restore it to 3.1.3

So I Have a 3GS
Network Not Available
Version: 3.1.2 (7D11)
Serial Number: XXX31XXXX
Model MC131B
Model FW: 05.12.01

I get the 1015 error when downgrading so I belive that means I have something saved on the Cydia Server?

I had it working fine until I used PKG Backup and it crashed and since then I can't get my official Carrier O2 back...so I've a jailbroken iphone that won't make calls!!

I've tried lots of different ways-last one was to restore shift the 3.1.2 fw twice after 1015 error on 2nd attempt,press ok, open quickpwn 22, hold pwr/home for 15 secs, then open up blackra1n rc3 and still NO Service

Yes, you can restore to 3.1.2 and jailbreak it. SIM unlock won't work, but I see you don't need it, because you are using official carrier.
So try to restore your iPhone. Then you get 1015 error don't press OK. Just use iRecovery.

ok i got the irecovery and it found the iphone, i typed in the commands and now i held pwr and home for 10 seconds and it has woken up. back to the piture of connecting to itunes and it says to insert a valid sim and unlock...do I just do that?

How did you end up booting the phone after you had restored and it was on the 'connect to iTunes'-logo?

Yes, you can do that if you want to. Or you can just jailbreak your phone with blackra1n or redsn0w. Take a look to tutorials.
Dhamien, that was a last stage than you need insert SIM card to activate your iPhone trought iTunes.

I meant, after the downgrade from 3.1.3 to 3.1.2 the phone gets stuck in recovery mode. How do you get the phone booted from there?
